接受MQL5中Python生成的套接字输出

Question

我创建了一个类似于以下的套接字文件,并希望MQL5必须读取套接字的输出.请参阅以下python代码;
daemon.py

import socket
#import arcpy

def actual_work():
    #val = arcpy.GetCellValue_management("D:\dem-merged\lidar_wsg84", "-95.090174910630012 29.973962146120652", "")
    #return str(val)
    return 'dummy_reply'


def main():
    sock = socket.socket( socket.AF_INET, socket.SOCK_DGRAM )
    try:
        sock.bind( ('127.0.0.1', 6666) )

        while True:
            data, addr = sock.recvfrom( 4096 )
            reply = actual_work()
            sock.sendto(reply, addr)
    except KeyboardInterrupt:
        pass
    finally:
        sock.close()


if __name__ == '__main__':
    main()

client.py

import socket
import sys


def main():
    sock = socket.socket( socket.AF_INET, socket.SOCK_DGRAM )
    sock.settimeout(1)
    try:
        sock.sendto('', ('127.0.0.1', 6666))
        reply, _ = sock.recvfrom(4096)
        print reply
    except socket.timeout:
        sys.exit(1)
    finally:
        sock.close()


if __name__ == '__main__':
    main()

请帮助我通过MQL5接受套接字的输出

EDITED

我只是想reply在MQL5中接受一个变量,这个变量由daemon.py.我怎么能这样做？假设我希望MQL5应该打印来自python的响应,如上例所示,我希望MQL5应该尽可能dummy_reply在字符串变量中给出输出.

ZeroMQ有可能吗？

我想client.py用MQL5来完成,而不是使用python.请帮我.

请找到一个运行示例。重要的元素是在发送回复之前创建有效负载的字节对象而不是字符串。套接字对象仅生成和摄取字节

    import socket

    def actual_work(data):
       print(data)

       sock.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1)
       sock.bind(('127.0.0.1', 6666))
       print("Listening on udp %s:%i" % ('127.0.0.1', 6666))
       try:

          while True:
              data, addr = sock.recvfrom(4096)
              ack = actual_work(data)
              sock.sendto(ack, addr)
       except Exception as e:
